Answer:
(x - 5)² = 17
Step-by-step explanation:
Given
0 = - x² + 10x - 8 ( multiply through by - 1 to clear the leading negative )
x² - 10x + 8 = 0 ( subtract 8 from both sides )
x² - 10x = - 8
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = - 8 + 25
(x - 5)² = 17
John went to an electronics store to purchase a new computer. The electronics store allowed John to make payments on the computer instead of paying the entire amount upfront. If John decides to purchase a computer that costs $1,260, and he makes 6 equal monthly payments, what would be his monthly payment?
Answer:
The monthly payment is $210
Step-by-step explanation:
The computation of the monthly payment is shown below:
Given that
The cost of the computer i.e. purchased is $1,260
And, there are 6 equal monthly payments
So, the monthly payment is
= Computer cost ÷ number of equal monthly payments made
= $1,260 ÷ 6 payments
= 210
hence, the monthly payment is $210 and the same is to be considered
EXTRA POINTS * how do you graph y=2x + 1
Step-by-step explanation:
first u need to pick a random coordinate to substitute the X . example 0
y = 2(0) + 1
y =1 , X= 0
X= 1
y= 2(1) + 1
y= 3, X= 1
then you continue this same process and again until u have at least two points to draw a straight line. it kinda depended if u want to fill the entire graph.

The sum of three consecutive even integers is 126. Let x represent the first integer, x + 2 represent the second integer, and x + 4 represent the third integer.
Which equation can be used to find the first integer?
3x + 126 = 2x + 6
3x + 6 = 126
2x + 6 = 126
3x = 2x + 6
Answer:
3x + 6 = 126
Step-by-step explanation:
If you add all of them
x + x+2 + x+4 = 126
simplify the left-side
3x+6=126
subtract 6 from both sides and you get
3x = 120
divide both sides by 3
x=4
Calculate the area of the triangle? What is the best way to solve it
Answer: Find the the height and length of the triangle. I'm not sure what it would be but then use a1 + a2 to find the area
Answer:
Formula of triangle: A = 1/2 x b x h
Step-by-step explanation:
Solve the base of the triangle by solving the distance between points (-2,0) and (f, -5) in units, and then do the same for height: find distance between points (-2, 6) and (-2, 0). Once you find the distance, input value of base and height into the formula and solve to get the area!

1) Explain what Pablo did in each step of his work.
2) Explain what Karla did in each step of his work.
3) Are Pablo and Karla correct?
Please help due today!!
Answer:
Pablo Used the Commutative property to Reorder the terms. Pablo then Combined all his like terms. Pablo then Divided 21 by 3x to get 3(7+x). Pablo then subtracted 7 from 13. He got x = 6
Pablo did his math wrong.
Karla Did her work correctly. Karla used the commutative property to reorder the terms. She then combined her like terms. She subtracted 21 from itself and 39, leaving 3x and 18 on different sides of the equal sign. She divided 3x by 3 which equals x and 18 by 3 which equals Karla is correct.
Step-by-step explanation:
The width of a rectangle is modeled by the function w(x) = 3x – 6, and the length of the rectangle is modeled by the function l(x) = 5x + 7. How can the functions be combined to find a function, a(x), that models the area of the rectangle?
a(x) = 8x + 1
a(x) = 16x + 2
a(x) = 15x2 – 9x – 42
a(x) = 30x2 – 18x – 84

your answer should be 2 and 1/4ths
Step-by-step explanation
2 and 1/4ths bc 5 is more than 4 and there is already a whole so there for there are going to be 2 wholes then there are still parts left over and its out of 4 and there is only one left over so there for it would be 1/4ths.

which statements are true about the polynomial function?
f(x)=x^3+5x^2+6x
Statements given in the Options (3) and (4) are the correct.
Polynomial function given in the question is,
f(x) = x³ + 5x² + 6x
Check all the options whether they are true or false.
Option (1)
f(x) = 0 at x = 2,
Substitute the value x = 2 in the polynomial.
f(2) = (2)³ + 5(2)² + 6(2)
= 8 + 20 + 12
= 40
False.
Option (2)
(x + 2) is a factor of f(x).
If it's true, f(x) = 0 will be true for x = -2
Substitute x = -2 in the function,
f(-2) = (-2)³ + 5(-2)² + 6(-2)
= -8 + 20 - 12
= -20 + 20
= 0
True.
Option (3)
f(-2) = 0
f(-2) = (-2)³ + 5(-2)² + 6(-2)
= -8 + 20 - 12
= 0
True.
Option (4)
f(x) divided by (x - 2) has a remainder of 0.
x - 2)x³ + 5x² + 6x(x² + 7x
x³ - 2x²
7x² + 6x
7x² - 14x
20x
Here, remainder is (20x).
False.
Therefore, Options (3) and (4) are correct.

Answer:
x=8
m<FGH=32
m<HGI=32
m<FGI=64
Step-by-step explanation:
The first thing you're going to do is form an equation using 5x-8 and 6x-16. The reason for this is because the two angles FGH and HGI are congruent. You form an equation by setting the two equal to each other. LIke this:
5x-8=6x-16
Then you will find x which is 8. After you find x just plug in x for one of the equations like so:
5(8)-8=_ or 6(8)-16=_
You only need to plug in x for one of the angles because they are congruent so you will get the same answer.
To find the measurment of FGI you add the values from FGH and HGI together (32+32) and you'll get 64.
